Flash Module
Functional
CPU AND DMA are not able to access the flash at the same time
CPU AND DMA cannot concurrently access the flash; this simultaneous access results in reading incorrect data from the flash.
Do not access the flash via CPU AND DMA concurrently. In case of typical Flash operations of program/erase operation, read verify/ blank verify operations, as well as the DMA reads from flash; software needs to make sure that CPU does not access flash while the flash is busy. This can be provided by putting code in SRAM while a flash operation is on-going or move the flash memory into SRAM for data the DMA needs to read.
